Way back in 1826, when life insurance was in its infancy, it was already apparent that many policies were being mis-sold.

Charles Babbage, better known as the inventor of the first programmable computer, but also actuary of the Protector Life Assurance Society of London, identified the fundamental problem with commission-based selling of financial products, which he likened to “the acceptance of a bribe”.

It is a system, said Babbage, that will inevitably “corrupt and debase those through whom it is carried on.”

What Babbage described is what economists have subsequently called the “agency problem”, and it is endemic to commission-based remuneration where the agent is supposed to be working in the best interest of the client, but will gain greatest personal benefit by selling the product that offers the largest commission.

It is present whether the product is insurance or financial advice or a mortgage.

The Royal Commission has shown that insurance companies, banks, brokers and advisers are prepared to trample on the trust placed in them by millions of Australians by putting their own income and interests ahead of their clients’.

The way professions have typically addressed the agency problem is by constructing a set of moral codes and formal regulations to prevent (or at least limit) bad behaviour.

Medics have their Hippocratic Oath; lawyers have their Code of Ethical Conduct, and in large measure they seem to work.

Insurers, bankers, brokers and financial planners have less formal codes of conduct, but it is now clear that they don’t work – they are little more than smokescreens to conceal self-interested avarice.

As Babbage noted almost two centuries ago, wherever financial products are sold on commission, the payment received by the agent or broker has all the characteristics of a bribe.

These habits of rapacity are so deeply ingrained in the culture and operation of financial institutions that no amount of self-regulation, no elaboration or reinforcement of voluntary codes of conduct, has been able to spare the sector from the corruption and debasement that Babbage foresaw.

More self-regulation won’t help. Here’s what would.

The Government should impose an outright ban on the payment of any commission of any kind with respect to any consumer financial transaction.

The cost of the work should be transparently priced and should be paid for at the point of delivery.

It would, at a stroke, end high-pressure selling and would reward financial advisers and brokers for the service they actually deliver to clients.

Those who deliver good advice would prosper. The rest would go out of business.

The idea lies at the heart of the banning of commissions in Labor’s Future of Financial Advice Act, which unfortunately did not extend its ban on commissions to those for insurance.

Second, where clients buy a financial product that charges an annual management fee, such as a superannuation account, the fee should be reported to the client in dollar terms rather than the percentage of funds under management.

Each year the client should be given the option of a “free transfer” of their funds to an alternative provider that can offer the same product for a lower fee.

It would open up the opaque structure of management fees to critical review by clients, and would impose competitive pressure to drive down fees, which in Australia’s bloated superannuation sector are more than double the OECD average.

Such reforms would be greeted with howls of protest from super funds (and banks, where banks still control them) but as Babbage foresaw and the Royal Commission has demonstrated, the industry has become so beholden to its own self-interest that it has forfeited the right to control its future.
